Science & Technology Mixed Quiz: Set 36

CL-20, HMX and LLM-105 are all powerful high explosives used in warheads, shells and military charges. HMX, also called octogen, is a nitramine explosive more powerful than RDX and is used in missile warheads and shaped charges.

LiFi (Light Fidelity) sends data wirelessly by switching LED light on and off far too fast for the eye to notice, and it can be many times faster than WiFi.

Majorana 1 is a quantum computing chip, but it was unveiled by Microsoft, not AWS; and deep learning is indeed a branch of machine learning.

These are the two general purpose detectors on the LHC ring, and in July 2012 both independently reported a new particle of about 125 giga-electronvolts that matched the Higgs boson, the particle linked to the field that gives mass to other particles; the Nobel Prize in Physics of 2013 went…

Tyres and tubes must carry the BIS mark, but AGMARK is an Indian government mark, not an FAO one. The Bureau of Indian Standards, set up under the BIS Act (now the BIS Act, 2016), runs the ISI mark scheme.

Cas9 is an enzyme that breaks the sugar-phosphate backbone of both DNA strands at the point where its guide RNA has bound, provided a short adjacent signal called the PAM is present.

All three describe the idea of Web 3.0: a decentralised internet where users own their data and run the platforms together.

A single proton, the nucleus of ordinary hydrogen, has a spin and therefore a magnetic moment, and hydrogen is by far the most abundant such nucleus in the body because the body is largely water and fat.

Pronuclear transfer is a mitochondrial replacement technique that stops a mother from passing faulty mitochondria to her child. Mitochondria have their own small DNA, inherited only from the mother; defects in it cause serious muscle, heart and brain diseases.

He developed the probe that made DNA fingerprinting practicable in India at the Centre for Cellular and Molecular Biology at Hyderabad, where the first Indian case used the technique in 1988; he later founded the Centre for DNA Fingerprinting and Diagnostics and served as Vice-Chancellor of Banaras Hindu University.

All four materials can be turned into Sustainable Aviation Fuel (SAF) through one or another approved conversion route. SAF is a jet fuel made from renewable or waste sources instead of crude oil, and it can be blended with ordinary aviation turbine fuel without changing aircraft engines.

The Bureau of Energy Efficiency was set up on 1 March 2002 under that Act and works under the Ministry of Power; its Standards and Labelling programme gives appliances a rating from one star to five stars, where more stars mean less electricity consumed for the same service.

Placed in a cavern under about 1,300 metres of rock at Pottipuram in the Bodi West Hills, it is designed to catch atmospheric neutrinos and measure how they change from one flavour to another, the phenomenon of neutrino oscillation; the magnetic field lets it tell a neutrino from an antineutrino.

In Mission Shakti an interceptor developed by the Defence Research and Development Organisation was launched from Dr. A. P. J. Abdul Kalam Island off the Odisha coast and destroyed India's own Microsat-R satellite in low Earth orbit at a height of about 283 kilometres.

The transcriptome is the complete set of RNA transcripts, chiefly messenger RNA, made from the genes at a given time.

The Antarctic Treaty was signed on 1 December 1959 by twelve nations that had been active in the continent during the International Geophysical Year, and it came into force in 1961.

With today's gene-editing and stem cell tools, all three procedures are technically possible. Changes made in germline cells, the cells that give rise to eggs or sperm, are passed on to the next generation, and tools such as CRISPR-Cas9 can make such edits.

When the driver lifts off or brakes, the electric motor is made to work backwards: the turning wheels drive it, it generates electricity, and that current is fed back into the pack.

Genetic medicines fix or make up for a faulty gene using delivery vehicles such as viruses and lipid nanoparticles, but they do not rewrite a person's whole DNA.

Their instruments, such as the giant sundial called the Samrat Yantra and the hemispherical Jai Prakash Yantra, measured time, declination and the positions of the planets with shadow and sightline alone, and the Jaipur site was inscribed on the UNESCO World Heritage List in 2010.
